▎ 摘　　要

NOVELTY - Manufacture of graphene material involves adding graphene oxide to dispersion medium, obtaining graphene oxide suspension, spray-drying resultant suspension and reducing graphene oxide particles under reducing atmosphere. USE - Manufacture of graphene material used as catalyst carrier, infrared optical material and electrode material of supercapacitor. ADVANTAGE - The method enables manufacture of graphene material having high porous structure with high productivity. The supercapacitor provided using the graphene material has high capacity of 120 F/g.
